Moore's Law: The performance of computer processors doubles every 18 months, while prices drop by half.
It has been decades since Moore proposed this empirical statement, and this law has always been fulfilled.
However, during this period, the domestic computer industry was still very underdeveloped, especially in the field of supercomputing. The most advanced supercomputer in the country at this time was the "Yinhe-2" that had just passed the national certification four years ago.
However, even this most advanced computer in the country can only perform one billion operations per second, which has no advantage compared with home CPUs thirty years later.
Not to mention being compared with those supercomputers that can run smoothly at the exascale level and have peak calculation times at the billions level.
Of course, compared with the protein computing units embedded in Zhang Xingyang's brain, these supercomputers are like grains of light that dare to compete with the bright moon.
In the 22nd century, brain computers are the same thing as mobile phones in the 21st century.
Taking the "Galaxy-5" computing unit embedded in Zhang Xingyang's brain as an example, the number of operations per second has reached the level of 10 to the 25th power.
It exceeds the most advanced "Galaxy-2" supercomputer at this time by more than ten orders of magnitude.
And its size is also surprisingly small, less than the thickness of a human hair.
In terms of computing power alone, Zhang Xingyang's computing power at this time actually exceeds the sum of almost all computers in the world combined.
Therefore, as long as he wanted to, he could get the correct answer in no more than a second when it came to the tail jet fluid problem during the rocket engine joint experiment.
However, Zhang Xingyang didn't really want to give the correct answer to this question to everyone who participated in this experiment.
After coming to this era, Zhang Xingyang has always had a clear understanding of the role he wants to play.
That is the role of the leader, or the teacher.
A truly good teacher will not only teach students the correct answers to questions but not teach them how to solve problems.
As the saying goes: It is better to teach a man to fish than to teach him to fish!
This principle is also applicable in the field of scientific research. It is better to teach them the solution to the problem than to directly give the result of the problem.
In particular, although everyone at the Rocket Research Institute has indeed done a lot of scientific research work during this year.
But many people are still far from being able to stand alone, whether in terms of design, control systems, or material research and development.
To be honest, if Zhang Xingyang hadn't been supporting them all the time, they wouldn't be able to do many things.
So this time, Zhang Xingyang decided to let them solve the problem of engine exhaust fluid by themselves.
Of course, Zhang Xingyang did not do anything. What he needed to bear was actually to help Geng Bo and Qiao Yang with the verification calculations after they established the tail jet fluid model.
Although the "Galaxy-5" protein chip in Zhang Xingyang's mind can be calculated in less than a second, if he actually does this, it will probably scare many people in the Rocket Research Institute.
After all, given the complexity of this model, it would take several years at least to calculate it simply using human power.
And you figure it out in one second, either you are lying or you are not a human being at all!
Therefore, in order to cover up one's own computing power, which does not seem very reasonable in this era, it is necessary to find a way to lend a supercomputer.
Come and conduct computer simulation experiments on the fluid operation model designed by Qiao Yang and others.
At this time in China, supercomputing is a very scarce resource, and not all projects can apply for it.
Generally, only key projects related to national key projects can apply for a certain period of time.
If you just use the name of the Rocket Research Institute, you may be able to apply for usage time of a supercomputer, but you will definitely have to queue up.
As for when it will be scheduled, only God knows.
After all, there are too many units in China that need to use supercomputing. The field of weather forecasting requires a lot of supercomputing time every day, and there are a lot of supercomputing waiting to be used in the military industry.
The field of missiles, which is more important than rockets, has always used high-performance supercomputers to conduct simulation experiments.
So in order to use the supercomputer in advance, Zhang Xingyang approached Mr. Chen, who was in charge of the Beidou navigation system.
The development of new rockets is itself closely related to the Beidou navigation system.
An important future task of the new rocket will be to launch satellites for the entire Beidou Phase III navigation system.
This is also the reason why Zhang Xingyang came to see Mr. Chen in the first place. This matter is really related to the follow-up progress of the Beidou navigation system.
Mr. Chen has a big reason to help the Rocket Research Institute gain supercomputer usage time.
"Mr. Chen, I still have to trouble you about super-calculated matters!"
Zhang Xingyang asked Mr. Chen very humbly and sincerely.
"You are really going to give me a hard time. There are only a few supercomputers in the country that can verify such confidential projects."
After drinking a cup of Longjing tea, Mr. Chen said with a smile:
"Now all units that have such needs are looking at those supercomputers almost all the time."
"It's really not easy to buy you a certain amount of time."
"Well, the Beidou project team itself also has certain supercomputer usage time indicators, and can give you some of them first."
Because Beidou is the first domestic satellite navigation system to be developed, it is allocated a certain amount of supercomputing time to conduct simulations and verify the status of satellites in orbit.
However, Zhang Xingyang knew that this part of the time must be very tight. It would take a lot of work for Mr. Chen to be able to squeeze out some of it for the Rocket Research Institute.
"Mr. Chen, thank you very much."
Zhang Xingyang said with some emotion:
"Actually, we can also apply for a certain amount of supercomputing usage time, but these times are relatively late in the queue."
"If we really wait slowly for supercomputer queues, it will be difficult to conduct test launches within next year."
Speaking of the development progress of the new rocket, Chen Zhongyan also became very interested.
Because if nothing unexpected happens, the first phase of the Beidou construction project will start next year.
The first phase of the project will actually launch only three orbiting satellites to form a relatively simple satellite navigation system.
Now I just don’t know whether the rocket newly developed by the Rocket Research Institute can be officially put into use during the first phase of construction.
"When will your newly developed rocket be ready for test firing? When will it be officially put into use?"
Regarding Mr. Chen's question, although it is not convenient for Zhang Xingyang to tell you some technical details, he can still talk about the development progress related to the construction of the Beidou navigation system.
